Given numbers are 240, 820, 640, 843

The list of prime factors of all numbers are

Prime factors of 240 are 2 x 2 x 2 x 2 x 3 x 5

Prime factors of 820 are 2 x 2 x 5 x 41

Prime factors of 640 are 2 x 2 x 2 x 2 x 2 x 2 x 2 x 5

Prime factors of 843 are 3 x 281

The above numbers do not have any common prime factor. So GCD is 1

Given numbers are 240, 820, 640, 843

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(240, 820) = 9840

GCD(240, 820) = ( 240 x 820 ) / 9840

= 240 / 820

= 240

Step2:

LCM(20, 640) = 640

GCD(20, 640) = ( 20 x 640 ) / 640

= 20 / 640

= 20

Step3:

LCM(20, 843) = 16860

GCD(20, 843) = ( 20 x 843 ) / 16860

= 20 / 843

= 20

So, Greatest Common Divisor of 240, 820, 640, 843 is 1
